Patent number: 8434738Abstract: Jack-type tools for moving elements such as flooring elements by pulling and, alternatively, by pushing are shown and described. In an embodiment, the jack includes a base, a puller pivotably attached to the base, a ram extendable from the base, and a ram-drive mechanism in power-transmission relationship with the ram which is operative to extend the ram. The pivotably attached puller contacts a flooring element side portion during a pulling mode of operation and pivots out of the way so that the jack can push a flooring element during a pushing mode of operation. The ram extends from the base against a fixed surface such as a wall or cabinet to apply a force which pulls the flooring element with the puller to move the puller and flooring element away from the fixed surface and, alternatively, a force which pushes the flooring element by extension of the ram with the tool secured with respect to a subfloor or other support.Type: GrantFiled: September 13, 2010Date of Patent: May 7, 2013Assignee: Powernail CompanyInventor: Todd J.

Patent number: 6290209Abstract: A pushing tool adapted to grip a joist and exert pushing force on a board located immediately above the joist. The tool comprises a block having a threaded bore, a screw which threads into the bore, and a clamp fixed to the block. Four arms forming dual parallelogram linkages are pivotally mounted to the block and to the jaws of the clamp such that when the block is drawn along the screw by screw action, the arms fold in the direction of parallel orientation relative to the screw. This draws the jaws of the clamp towards one another such that they engage and grip the joist. The jaws of the clamp have cleats preventing the jaws from slipping ineffectually along the joist. Continued rotation of the screw advances the screw against the board located above the joist. Pitch of the threading of the bore and the screw enable great pressure to be exerted on the board when the screw is turned by a wrench.Type: GrantFiled: February 25, 2000Date of Patent: September 18, 2001Inventor: James E.

Patent number: 5533709Abstract: A woodworking press for effecting a mating of jointed boards. The instant invention is an elongated pressing/jacking device which includes, at one end, an anchor piece, at the other end a reversible head for contact of a workpiece and a central turnbuckle structure connecting the anchor and the head. The anchor is adapted for nailing to a substrate and has a feature to enhance prying the anchor from the substrate. The turnbuckle device is conventional, but is enhanced by use of a transfixed, shuttling handle. The head is unique in that it is designed having multiple edges which may be brought into mating contact with wood joint structures of varying morphology. Through use of a simple, yet elegant, connection mechanism, the head may be alternately positioned so as to present different mating configurations to the workpiece.Type: GrantFiled: September 8, 1995Date of Patent: July 9, 1996Inventor: Russell Tarbell
